See Summer Triangle in west on winter evenings

10dec25_430

Tonight for December 24, 2011

In the west shortly after sunset around now, you’ll find a famous asterism – a noticeable pattern of stars, not a constellation – known as the Summer Triangle.

Moon and Venus night after Christmas, all five planets visible

The Triangle consists of three bright stars in three different constellations. They are Vega in the constellation Lyra the Harp, Deneb in the constellation Cygnus the Swan, and Altair in the constellation Aquila the Eagle. It’s called the “summer” triangle, because – for us in the northern hemisphere – summer is the season in which these stars soar overhead.

Still, if you look for this pattern this month, you’ll find that, around the time of the winter solstice, the Summer Triangle is descending in the west in early evening. It’s getting closer each evening to disappearing into the sunset glare.

How long into winter will you be able to see the Summer Triangle in your evening sky?

    I enjoy hearing E & S on FM radio WUMB Boston. I don’t hear it every day. Can I subscribe to a written, daily broadcast, and/or a voice podcast. How can I get a repeat of Dec. 23, 2011 and the North Pole moving north @ 40 miles per year?
    Merry Christmas to you all.
